Description

本発明は、ハウジングと、ハウジングに組み付けられるシーリング部品と、を備えるコネクタ、及び、そのようなコネクタの製造方法に関する。 TECHNICAL FIELD The present invention relates to a connector including a housing and a sealing component assembled to the housing, and a method for manufacturing such a connector.

従来から、コネクタの止水性を向上させる等の観点から、シーリング部品（パッキン等）がハウジングに組み付けられたコネクタが提案されている。例えば、従来のコネクタの一つは、シーリング部品であるパッキンから延びる柱状の係止部を、ハウジングに設けた係止孔に挿入して係合させることで、シーリング部品をハウジングに組み付けるようになっている（例えば、特許文献１〜３を参照）。 2. Description of the Related Art Conventionally, a connector in which a sealing component (packing or the like) is assembled in a housing has been proposed from the viewpoint of improving the waterproof property of the connector. For example, in one of the conventional connectors, a columnar locking portion extending from a packing that is a sealing component is inserted into a locking hole provided in the housing and engaged with the sealing component so that the sealing component is assembled to the housing. (See, for example, Patent Documents 1 to 3).

特開２０１０−０９２６１４号公報JP, 2010-092614, A 特開平１−０９５４７５号公報JP, 1-095475, A 特開平９−１２９３０３号公報JP, 9-129303, A

上述した従来のコネクタに用いられるシーリング部品が有する柱状の係止部は、基端側から先端側に向けて徐々に細くなる先細り形状（換言すると、矢尻状の形状）を有する先端箇所と、先端箇所よりも小径であり且つシーリング部品の本体部に向けて延びる柱状箇所（首状の箇所）と、を有している。係止部の先端箇所（矢尻状の箇所）は、ハウジングの係止孔よりも大径となっている。そして、ハウジングの係止孔に係止部の先端箇所を挿通させるとともに、先端箇所を係止孔に引っ掛けることで、シーリング部品がハウジングに固定されるようになっている。 The columnar locking portion included in the sealing component used in the above-described conventional connector has a tip end portion having a tapered shape (in other words, an arrowhead-like shape) that gradually narrows from the base end side toward the tip end side, and the tip end. And a columnar portion (neck-shaped portion) having a smaller diameter than the portion and extending toward the main body of the sealing component. The tip portion (arrow-shaped portion) of the locking portion has a larger diameter than the locking hole of the housing. The sealing part is fixed to the housing by inserting the tip part of the locking part into the locking hole of the housing and hooking the tip part in the locking hole.

ところで、通常、シーリング部品は、止水性を高める等の観点から、コネクタと相手側コネクタとに挟まれた際に変形し得る程度に柔軟性のある材料（例えば、ゴム等）から構成される。ところが、係止部の先端箇所（矢尻状の箇所）をハウジングの係止孔に挿通させるとき、この柔軟性に起因し、係止部の柱状箇所（首状の箇所）が意図せずランダムな方向に曲がってしまい、ハウジングへのシーリング部品の組み付けが困難となる場合がある。 By the way, the sealing component is usually made of a material (for example, rubber) that is flexible enough to be deformed when it is sandwiched between the connector and the mating connector, from the viewpoint of improving the waterproofness. However, when the tip end portion (arrow-shaped portion) of the locking portion is inserted into the locking hole of the housing, due to this flexibility, the columnar portion (neck-shaped portion) of the locking portion is unintentionally random. It may bend in the direction, which may make it difficult to assemble the sealing component to the housing.

このような係止部の意図しない湾曲への対策として、シーリング部品を硬質な材料で構成することが考えられる。しかし、この場合、先端箇所（矢尻状の箇所）が硬くなることで係止孔に先端箇所を挿通させ難くなり、且つ、シーリング部品の本体部も硬くなることで本来の機能である止水性が損なわれる可能性もある。このように、従来のコネクタでは、ハウジングとシーリング部品との組み付けの容易さと、シーリング部品による止水性の向上と、の両立が困難であった。 As a countermeasure against such an unintended bending of the locking portion, it is conceivable that the sealing component is made of a hard material. However, in this case, since the tip portion (arrow-shaped portion) becomes hard, it becomes difficult to insert the tip portion into the locking hole, and the main body of the sealing component also becomes hard, so that the original function of waterproofing is prevented. It may be damaged. As described above, in the conventional connector, it is difficult to achieve both easy assembling of the housing and the sealing component and improvement of the waterproof property by the sealing component.

本発明は、上述した事情に鑑みてなされたものであり、その目的は、ハウジングとシーリング部品との組み付けの容易さと、シーリング部品による止水性の向上と、を両立可能なコネクタ、及び、そのようなコネクタの製造方法、を提供することにある。 The present invention has been made in view of the above-mentioned circumstances, and an object thereof is a connector capable of achieving both easy assembly of a housing and a sealing component and improvement of water blocking performance by the sealing component, and such. Another object of the present invention is to provide a method for manufacturing such a connector.

上記［１］の構成のコネクタによれば、ハウジングとシーリング部品との組み付けの際、シーリング部品から延びる柱状の係止部の先端箇所（例えば、従来のコネクタにおける矢尻状の箇所）があらかじめ設計された（即ち、従来のコネクタのようなランダムではない）「所定の向き」に傾くように、係止部の柱状箇所（例えば、従来のコネクタにおける首状の箇所）が湾曲する。係止部の先端箇所は、柱状箇所が湾曲していない状態にて柱軸方向から見たときの先端箇所の大きさ（例えば、図６等に示す断面における幅。最大断面積とも言い得る）よりも、柱状箇所が湾曲して先端箇所が柱軸方向に対して「所定の向き」に傾いた状態にて柱軸方向から見たときの先端箇所の大きさ（例えば、断面における幅）の方が小さい。そのため、係止部の先端箇所が「所定の向き」に傾くことで、先端箇所がハウジングの係止孔を通り易くなる。 According to the connector of the configuration [1], when the housing and the sealing component are assembled, the tip end portion of the columnar locking portion extending from the sealing component (for example, the arrowhead-shaped portion in the conventional connector) is designed in advance. The columnar portion (for example, the neck-shaped portion in the conventional connector) of the locking portion is curved so as to tilt in a “predetermined direction” (that is, not in a random direction as in the conventional connector). The tip portion of the locking portion is the size of the tip portion when viewed from the column axis direction in the state where the column portion is not curved (for example, the width in the cross section shown in FIG. 6 or the like, which can also be called the maximum cross-sectional area). Than the size of the tip portion (for example, width in cross section) when viewed from the column axis direction in a state where the column portion is curved and the tip portion is inclined in the “predetermined direction” with respect to the column axis direction. The smaller one. Therefore, the tip portion of the locking portion is inclined in the “predetermined direction”, so that the tip portion easily passes through the locking hole of the housing.

換言すると、シーリング部品を柔軟な材料で構成した場合であっても、従来のコネクタのように係止部がランダムな方向に湾曲するのではなく、先端箇所が係止孔を通り易くなる「所定の向き」に係止部が湾曲するため、両者の組み付けを適正に行い得る。また、仮にシーリング部品をある程度硬質な材料で構成しても、上述したように先端箇所が係止孔を通り易いため、両者の組み付けを適正に行い得る。 In other words, even when the sealing component is made of a flexible material, the locking portion does not bend in a random direction unlike the conventional connector, but the tip portion easily passes through the locking hole. Since the locking portion is curved in the "direction", both can be properly assembled. Further, even if the sealing component is made of a material that is hard to some extent, the tip portion easily passes through the locking hole as described above, so that the both can be properly assembled.

このように、本構成のコネクタは、係止部が湾曲する向きを意図的に制御することで、ハウジングとシーリング部品との組み付けの容易さと、シーリング部品による止水性の向上と、を両立可能となっている。 As described above, the connector of the present configuration makes it possible to achieve both easy assembly of the housing and the sealing component and improvement of the waterproof property by the sealing component by intentionally controlling the bending direction of the locking portion. Has become.

上記［２］の構成のコネクタによれば、係止部の柱状箇所に窪み（例えば、切り欠き）が設けられ、この窪みを起点として先端箇所が「所定の向き」に傾く。よって、窪みの位置や大きさ等を調整することで、先端箇所の傾きを任意に制御できることになる。 According to the connector of the above [2], a recess (for example, a notch) is provided in the columnar portion of the locking portion, and the tip end portion is inclined in the “predetermined direction” with the recess as the starting point. Therefore, the inclination of the tip end portion can be arbitrarily controlled by adjusting the position and size of the depression.

上記［３］の構成のコネクタによれば、係止孔の孔内面のうちの係止部の窪みに向かい合う部分が、柱軸方向に対して「所定の向き」に傾いた軸方向（以下「傾斜軸方向」ともいう。）に沿うように傾いている。よって、窪みを起点に係止部の柱状箇所が湾曲し、湾曲した柱状箇所が孔内面に向けて突出しても、柱状箇所が孔内面に突き当たり難い。逆に言えば、孔内面が柱状箇所の湾曲の妨げになり難い。よって、係止部の先端箇所が「所定の向き」に傾くように、柱状箇所を適正に湾曲させることができる。 According to the connector of the above [3], the portion of the inner surface of the locking hole that faces the recess of the locking portion is axially inclined in a “predetermined direction” with respect to the column axial direction (hereinafter referred to as “the predetermined direction”). Also referred to as the "tilt axis direction"). Therefore, even if the columnar portion of the locking portion is curved starting from the recess and the curved columnar portion projects toward the inner surface of the hole, the columnar portion is unlikely to hit the inner surface of the hole. Conversely speaking, the inner surface of the hole is unlikely to hinder the curvature of the columnar portion. Therefore, the columnar portion can be appropriately curved so that the tip portion of the locking portion is inclined in the “predetermined direction”.

上記［４］の構成のコネクタによれば、係止部の先端箇所と窪みとが連続するように、窪みが設けられている。ここで、仮に、係止部の先端箇所と窪みとが離れていると、係止部が湾曲した際、先端箇所と窪みとの間にある部分が係止孔の孔内面に向けて突出し、この部分と孔内面とが接触する可能性がある。この接触に起因し、例えば、先端箇所が係止孔を通過し難くなる懸念がある。しかし、係止部の先端箇所と窪みとが連続する場合、このような懸念を無くすことができる。よって、ハウジングとシーリング部品との組み付けを更に適正に行い得る。 According to the connector of the above [4], the recess is provided so that the tip portion of the locking portion and the recess are continuous. Here, if the tip portion of the locking portion and the recess are separated, when the locking portion is curved, the portion between the tip portion and the recess projects toward the inner surface of the locking hole, This portion may come into contact with the inner surface of the hole. Due to this contact, for example, there is a concern that it becomes difficult for the tip portion to pass through the locking hole. However, when the tip portion of the locking portion and the depression are continuous, such a concern can be eliminated. Therefore, the housing and the sealing component can be more properly assembled.

上記［５］の構成のコネクタによれば、係止孔を柱軸方向から見たときの係止孔の開口の大きさ（例えば、図６等に示す断面における幅。開口面積とも言い得る）よりも、係止孔を傾斜軸方向から見たときの係止孔の開口の大きさ（例えば、断面における幅）が大きい。よって、係止部の先端箇所が傾斜軸に沿った「所定の向き」に傾くことによる組み付け性の向上に加え、係止孔の見かけ上の開口の大きさが増大することにより、更にハウジングとシーリング部品との組み付けを適正に行い得る。 According to the connector of the above [5], the size of the opening of the locking hole when the locking hole is viewed from the column axis direction (for example, the width in the cross section shown in FIG. 6 or the like, which can also be called the opening area). The size of the opening of the locking hole (for example, the width in cross section) when the locking hole is viewed from the direction of the tilt axis is larger than that. Therefore, in addition to the improvement of the assembling property by inclining the tip end portion of the engaging portion in the “predetermined direction” along the inclination axis, the apparent opening size of the engaging hole is increased, and the housing is further The assembly with the sealing component can be properly performed.

上記［６］の構成のコネクタの製造方法によれば、ハウジングとシーリング部品との組み付けの際、シーリング部品から延びる柱状の係止部の先端箇所があらかじめ設計された「所定の向き」に傾くように、係止部の柱状箇所が湾曲する。係止部の先端箇所は、柱状箇所が湾曲していない状態にて柱軸方向から見たときの先端箇所の大きさよりも、柱状箇所が湾曲して先端箇所が柱軸方向に対して「所定の向き」に傾いた状態にて柱軸方向から見たときの先端箇所の大きさの方が小さい。そのため、係止部の先端箇所が「所定の向き」に傾くことで、先端箇所がハウジングの係止孔を通り易くなる。換言すると、シーリング部品を柔軟な材料で構成した場合であっても、従来のコネクタのように係止部がランダムな方向に曲がるのではなく、先端箇所が係止孔を通り易くなる「所定の向き」に係止部が湾曲するため、両者の組み付けを適正に行い得る。また、シーリング部品をある程度硬質な材料で構成しても、上述したように先端箇所が係止孔を通り易いため、両者の組み付けを適正に行い得る。 According to the connector manufacturing method of the above [6], when the housing and the sealing component are assembled, the tip end portion of the columnar locking portion extending from the sealing component is inclined in a predesigned “predetermined direction”. Moreover, the columnar portion of the locking portion is curved. The tip portion of the locking portion has a columnar portion that is curved and the tip portion is "predetermined" in the column axis direction more than the size of the tip portion when viewed from the column axis direction in a state where the column portion is not curved. The size of the tip is smaller when viewed in the column axis direction when tilted in the "direction". Therefore, the tip portion of the locking portion is inclined in the “predetermined direction”, so that the tip portion easily passes through the locking hole of the housing. In other words, even when the sealing component is made of a flexible material, the locking portion does not bend in a random direction unlike the conventional connector, but the tip portion easily passes through the locking hole. Since the locking portion is curved in the "direction", the both can be properly assembled. Further, even if the sealing component is made of a material having a certain degree of hardness, since the tip portion easily passes through the locking hole as described above, the both can be properly assembled.

このように、本構成のコネクタの製造方法は、係止部が湾曲する向きを意図的に制御することで、ハウジングとシーリング部品との組み付けの容易さと、シーリング部品による止水性の向上と、を両立可能となっている。 As described above, the method of manufacturing the connector of the present configuration intentionally controls the direction in which the locking portion bends, thereby facilitating the assembling of the housing and the sealing component and improving the waterproofness of the sealing component. It is compatible.

上記［７］の構成のコネクタの製造方法によれば、係止部の柱状箇所に窪み（例えば、切り欠き）が設けられ、この窪みを起点として先端箇所が「所定の向き」に傾く。よって、窪みの位置や大きさ等を調整することで、先端箇所の傾きを任意に制御できることになる。 According to the method of manufacturing a connector of the above [7], a recess (for example, a notch) is provided in the columnar portion of the locking portion, and the tip portion inclines in a “predetermined direction” from this recess. Therefore, the inclination of the tip end portion can be arbitrarily controlled by adjusting the position and size of the depression.

上記［８］の構成のコネクタの製造方法によれば、ハウジングの係止孔が、係止孔の孔内面のうち係止部の窪みに向かい合う第１面が、傾斜軸方向に沿うように傾斜し、且つ、柱状箇所を挟んで第１面に向かい合う第２面が、柱軸方向に交差して第１面に近付く向きに突出する、ようになっている（例えば、図６等の断面を参照）。これにより、係止部の先端箇所が係止孔に挿通される際、まず、先端箇所を第２面（第１面と逆側の面）に接触させることによって先端箇所を柱軸方向に対してオフセットさせて第１面に近付けるように変位させた後、先端箇所を第１面に接触させることによって先端箇所を「所定の向き」に傾けることができる。発明者による検討によれば、このように係止部の先端箇所を一旦オフセットさせた後に係止部の柱状箇所を湾曲させることで、係止部が湾曲する向きを適正に制御できることが明らかになっている。よって、本構成の製造方法により、ハウジングとシーリング部品との組み付けを更に適正に行い得る。 According to the connector manufacturing method of the above [8], the locking hole of the housing has the first surface of the hole inner surface of the locking hole facing the recess of the locking portion tilted along the tilt axis direction. In addition, the second surface facing the first surface across the columnar portion projects in a direction that intersects the column axis direction and approaches the first surface (for example, a cross section in FIG. 6 or the like). reference). As a result, when the tip end portion of the engaging portion is inserted into the engagement hole, first, the tip end portion is brought into contact with the second surface (the surface opposite to the first surface) to move the tip end portion in the column axial direction. After offsetting and displacing so as to approach the first surface, the tip portion can be tilted in the “predetermined direction” by bringing the tip portion into contact with the first surface. According to the study by the inventor, it is apparent that the bending direction of the locking portion can be appropriately controlled by offsetting the tip end portion of the locking portion once and then bending the columnar portion of the locking portion. Has become. Therefore, according to the manufacturing method of this configuration, the housing and the sealing component can be assembled more properly.

本発明によれば、ハウジングとシーリング部品との組み付けの容易さと、シーリング部品による止水性の向上と、を両立可能なコネクタ、及び、そのようなコネクタの製造方法を提供できる。 ADVANTAGE OF THE INVENTION According to this invention, the connector which can make the assembling of a housing and a sealing component easy, and the improvement of the waterproofness by a sealing component can be compatible, and the manufacturing method of such a connector can be provided.

＜実施形態＞
以下、図面を参照しながら、本発明の実施形態に係るコネクタ１について説明する。図１に示すように、コネクタ１は、ハウジング２と、ハウジング２に組み付けられるパッキン３と、を有する。パッキン３が組み付けられたハウジング２（図６（ａ）も参照）が、相手側ハウジング４と嵌合することで、ハウジング２に収容される端子（図示省略）と相手側ハウジング４に収容される端子（図示省略）とが電気的に接続され、且つ、パッキン３により、ハウジング２及び相手側ハウジング４の嵌合部分の止水機能が発揮される。 <Embodiment>
Hereinafter, a connector 1 according to an embodiment of the present invention will be described with reference to the drawings. As shown in FIG. 1, the connector 1 has a housing 2 and a packing 3 assembled to the housing 2. When the housing 2 (see also FIG. 6A) to which the packing 3 is assembled is fitted to the mating housing 4, the terminals (not shown) housed in the housing 2 and the mating housing 4 are housed. The terminals (not shown) are electrically connected, and the packing 3 exerts the water blocking function of the fitting portions of the housing 2 and the mating housing 4.

以下、説明の便宜上、図１〜図６に示すように、「前後方向」、「幅方向」、「上下方向」、「前」、及び「後」を定義する。「前後方向」、「幅方向」及び「上下方向」は、互いに直交している。前後方向は、ハウジング２と相手側ハウジング４との嵌合方向、及び、パッキン３のハウジング２への組付方向（柱軸方向）、と一致している。以下、コネクタ１を構成するハウジング２及びパッキン３について順に説明する。 Hereinafter, for convenience of description, as shown in FIGS. 1 to 6, “front-back direction”, “width direction”, “up-down direction”, “front”, and “rear” are defined. The "front-back direction", "width direction" and "up-down direction" are orthogonal to each other. The front-rear direction coincides with the fitting direction of the housing 2 and the mating housing 4 and the assembling direction of the packing 3 to the housing 2 (column axial direction). Hereinafter, the housing 2 and the packing 3 forming the connector 1 will be described in order.

まず、ハウジング２について説明する。樹脂製のハウジング２は、図１、図２及び図３に示すように、前後方向に延びる筒状の外筒部１１を有する。外筒部１１は、後端が開口し、前端開口が前端壁１２によって塞がれている。 First, the housing 2 will be described. As shown in FIGS. 1, 2 and 3, the resin housing 2 has a tubular outer tubular portion 11 extending in the front-rear direction. The outer cylinder portion 11 has a rear end opened and a front end opening closed by a front end wall 12.

外筒部１１の内部空間には、前端壁１２から後方に突出する略直方体状の端子収容部１３が位置している。端子収容部１３には、複数（本例では、４つ）の端子（図示省略）が収容されるようになっている。外筒部１１の内壁と端子収容部１３の外壁との間には、環状隙間１４が形成されている。この環状隙間１４には、パッキン３及び相手側ハウジング４の筒状部５（図１参照）が挿入されることになる。 A substantially rectangular parallelepiped terminal accommodating portion 13 that projects rearward from the front end wall 12 is located in the internal space of the outer tubular portion 11. A plurality of (four in this example) terminals (not shown) are accommodated in the terminal accommodating portion 13. An annular gap 14 is formed between the inner wall of the outer tubular portion 11 and the outer wall of the terminal accommodating portion 13. The packing 3 and the tubular portion 5 (see FIG. 1) of the mating housing 4 are inserted into the annular gap 14.

前端壁１２における四隅近傍箇所には、それぞれ、前後方向に貫通し且つ環状隙間１４に連通する係止孔１５が形成されている（図１も参照）。図３（ａ）及び図３（ｂ）に示すように、係止孔１５の孔内面のうち幅方向外側の面（図３（ｂ）において右側の面）は、前後方向且つ上下方向に沿う平面である外側面１６と、外側面１６の後端部１８から連続して後方且つ幅方向外側に向けて傾斜して延びる平面である外側斜面１７と、で構成されている。 Locking holes 15 are formed near the four corners of the front end wall 12 so as to penetrate in the front-rear direction and communicate with the annular gap 14 (see also FIG. 1 ). As shown in FIGS. 3(a) and 3(b), of the hole inner surfaces of the locking hole 15, the surface on the outer side in the width direction (the surface on the right side in FIG. 3(b)) extends in the front-rear direction and the vertical direction. The outer surface 16 is a flat surface, and the outer slant surface 17 is a flat surface extending continuously from the rear end portion 18 of the outer surface 16 toward the rear and outward in the width direction.

係止孔１５の孔内面のうち幅方向内側の面（図３（ｂ）において左側の面）には、外側面１６の後端部１８より後側の位置にて、外側斜面１７に近づくように幅方向外側に向けて突出する突部１９が設けられている。突部１９の表面は、前後方向且つ上下方向に沿う平面である頂面２１と、幅方向且つ上下方向に沿う平面である前端面２２と、頂面２１の後端部から連続して後方且つ幅方向内側に向けて傾斜して延びる平面である内側斜面２３と、で構成されている。この突部１９の前端面２２が、パッキン３のハウジング２への組み付け完了状態にて、パッキン３の後述する先端箇所３５の後端面４１（図４（ｂ）及び図６（ｂ）参照）を係止することになる。以上、ハウジング２について説明した。 Of the inner surface of the locking hole 15, the inner surface in the width direction (the surface on the left side in FIG. 3B) is located closer to the outer inclined surface 17 at a position rearward of the rear end portion 18 of the outer surface 16. Is provided with a protrusion 19 protruding outward in the width direction. The surface of the protrusion 19 is a top surface 21 that is a flat surface that extends in the front-rear direction and the up-down direction, a front end surface 22 that is a flat surface that extends in the width direction and the up-down direction, and rearward and continuously from the rear end portion of the top surface 21. The inner inclined surface 23 is a flat surface that is inclined and extends inward in the width direction. The front end surface 22 of the projection 19 is attached to the housing 2 of the packing 3 in a completed state, and the rear end surface 41 (see FIGS. 4B and 6B) of a front end portion 35 of the packing 3 described later is referred to. It will be locked. The housing 2 has been described above.

次いで、パッキン３について説明する。ゴム製のパッキン３は、図１、図２及び図４に示すように、筒状の本体部３１を有する。本体部３１の前端面（環状の面）におけるハウジング２の４つの係止孔１５に対応する箇所には、それぞれ、前方に突出する柱状の係止部３２が一体に設けられている。本体部３１の後端部の外周には、径方向外側に突出する環状のリップ部３３が一体で形成されている。 Next, the packing 3 will be described. The rubber packing 3 has a tubular main body 31 as shown in FIGS. 1, 2, and 4. Columnar locking portions 32 projecting forward are integrally provided at locations corresponding to the four locking holes 15 of the housing 2 on the front end surface (annular surface) of the main body portion 31. An annular lip portion 33 is integrally formed on the outer periphery of the rear end portion of the main body portion 31 so as to project radially outward.

図４（ａ）及び図４（ｂ）に示すように、係止部３２は、本体部３１から柱状に前方に突出する柱状箇所３４と、柱状箇所３４の先端部（前端部）に連続する先端箇所３５とを有する。先端箇所３５における幅方向外側面（図４（ｂ）において右側の面）は、前後方向且つ上下方向に沿う平面である外側面３６で構成されている。先端箇所３５における幅方向内側面（図４（ｂ）において左側の面）には、幅方向内側に向けて突出する突部３７が設けられている。 As shown in FIGS. 4A and 4B, the locking portion 32 is continuous with a columnar portion 34 protruding forward from the main body 31 in a columnar shape, and a tip portion (front end portion) of the columnar portion 34. And a tip portion 35. An outer side surface in the width direction (a right side surface in FIG. 4B) at the tip end portion 35 is an outer side surface 36 that is a plane extending in the front-rear direction and in the vertical direction. A projecting portion 37 that projects inward in the width direction is provided on the inner surface in the width direction at the tip portion 35 (the surface on the left side in FIG. 4B).

突部３７の表面は、前後方向且つ上下方向に沿う平面である頂面３８と、頂面３８の前端部から連続して前方且つ幅方向外側に向けて傾斜して延びる平面である斜面３９と、幅方向且つ上下方向に沿う平面である後端面４１と、で構成されている。 The surface of the protrusion 37 includes a top surface 38 that is a flat surface extending in the front-rear direction and the up-down direction, and a slope surface 39 that is a flat surface that continuously extends forward from the front end portion of the top surface 38 and extends outward in the width direction. , And a rear end surface 41 which is a flat surface extending in the width direction and the vertical direction.

柱状箇所３４の幅方向外側面の前端部には、先端箇所３５の外側面３６の後端部から連続するように、幅方向内側に窪んだ窪み４２が形成されている。この窪み４２の存在により、柱状箇所３４において窪み４２が形成された箇所の肉厚（幅方向の厚み）が局所的に小さくなっている。このため、柱状箇所３４が幅方向に湾曲する場合、柱状箇所３４は、窪み４２を起点して湾曲するようになっている。以上、パッキン３について説明した。 At the front end portion of the width direction outer side surface of the columnar portion 34, a recess 42 that is recessed in the width direction inner side is formed so as to be continuous from the rear end portion of the outer side surface 36 of the tip end portion 35. Due to the presence of the depression 42, the wall thickness (thickness in the width direction) of the columnar portion 34 where the depression 42 is formed is locally reduced. Therefore, when the columnar portion 34 is curved in the width direction, the columnar portion 34 is configured to be curved starting from the recess 42. The packing 3 has been described above.

次いで、パッキン３のハウジング２への組み付けについて説明する。パッキン３をハウジング２へ組み付けるには、まず、パッキン３の本体部３１をハウジング２の環状隙間１４に挿入する。次いで、パッキン３の４本の係止部３２をハウジング２の複数の係止孔１５にそれぞれ挿入する。そして、図６（ａ）及び図６（ｂ）に示すように、係止部３２の先端箇所３５の突部３７の後端面４１が係止孔１５の突部１９の前端面２２に係止されるまで、パッキン３をハウジング２に対して前方に押し込む。 Next, the assembling of the packing 3 into the housing 2 will be described. To assemble the packing 3 into the housing 2, first, the main body 31 of the packing 3 is inserted into the annular gap 14 of the housing 2. Next, the four locking portions 32 of the packing 3 are inserted into the plurality of locking holes 15 of the housing 2, respectively. Then, as shown in FIGS. 6A and 6B, the rear end surface 41 of the projection 37 of the tip end portion 35 of the locking portion 32 is locked to the front end surface 22 of the projection 19 of the locking hole 15. Until the packing 3 is pushed forward with respect to the housing 2.

これにより、パッキン３のハウジング２への組み付けが完了し、コネクタ１が得られる。パッキン３の組み付け完了状態（図６（ａ）参照）では、後端面４１と前端面２２との係止により、パッキン３のハウジング２からの脱落が防止される。なお、パッキン３のハウジング２への組み付けの際における、パッキン３の係止部３２の弾性変形の態様の推移については、図５を参照しながら後に詳述する。 As a result, the assembly of the packing 3 into the housing 2 is completed, and the connector 1 is obtained. When the packing 3 is completely assembled (see FIG. 6A), the rear end surface 41 and the front end surface 22 are locked to prevent the packing 3 from coming off the housing 2. The transition of the elastic deformation of the locking portion 32 of the packing 3 when the packing 3 is assembled to the housing 2 will be described later in detail with reference to FIG.

パッキン３の組み付け完了状態にあるハウジング２の環状隙間１４に、相手側ハウジング４の筒状部５（図１参照）が嵌合されると、パッキン３の環状のリップ部３３が筒状部５の内周面に全周に亘って密着することで、ハウジング２及び相手側ハウジング４の嵌合部分の止水機能が発揮される。 When the tubular portion 5 (see FIG. 1) of the mating housing 4 is fitted into the annular gap 14 of the housing 2 in which the packing 3 is in the assembled state, the annular lip portion 33 of the packing 3 is moved to the tubular portion 5. By closely contacting the inner peripheral surface of the housing over the entire circumference, the water blocking function of the fitting portion of the housing 2 and the mating housing 4 is exerted.

次いで、図６（ｂ）を参照しながら、ハウジング２の係止孔１５とパッキン３の係止部３２との寸法関係を説明する。図６（ｂ）に示すように、柱状箇所３４が湾曲していない状態にて、前後方向（柱軸方向）Ｌ１から見たときの先端箇所３５の幅寸法ａ（外側面３６と頂面３８との間隔）は、前後方向Ｌ１から見たときの係止孔１５の開口幅寸法ｃ（外側面１６と頂面２１との間隔）より大きい（ｃ＜ａ）。 Next, the dimensional relationship between the locking hole 15 of the housing 2 and the locking portion 32 of the packing 3 will be described with reference to FIG. As shown in FIG. 6B, the width dimension a (the outer side surface 36 and the top surface 38) of the tip end portion 35 when viewed from the front-rear direction (column axial direction) L1 in a state where the columnar portion 34 is not curved. Is larger than the opening width dimension c of the locking hole 15 when viewed from the front-rear direction L1 (the distance between the outer surface 16 and the top surface 21) (c<a).

なお、説明の便宜上、図６（ａ）及び図６（ｂ）では、図示された断面上での先端箇所３５の「幅」と係止孔１５の開口「幅」寸法との大小関係が示されている。しかし、これら幅に対応する先端箇所３５の「断面積」や係止孔１５の「開口面積」も、これら幅と同様の大小関係を有している。即ち、柱状箇所３４が湾曲していない状態にて、前後方向（柱軸方向）Ｌ１から見たときの先端箇所３５の最大断面積ｘは、前後方向Ｌ１から見たときの係止孔１５の開口面積ｙより大きい（ｙ＜ｘ）。後述する各種の「幅」についても、同様である。 For convenience of explanation, FIGS. 6A and 6B show the magnitude relation between the “width” of the tip end portion 35 and the opening “width” dimension of the locking hole 15 on the illustrated cross section. Has been done. However, the “cross-sectional area” of the tip portion 35 and the “opening area” of the locking hole 15 corresponding to these widths also have the same magnitude relationship as these widths. That is, the maximum cross-sectional area x of the tip portion 35 when viewed from the front-rear direction (column axis direction) L1 is the maximum cross-sectional area x of the locking hole 15 when viewed from the front-rear direction L1 in the state where the columnar part 34 is not curved. It is larger than the opening area y (y<x). The same applies to various “widths” described below.

柱状箇所３４が湾曲していない状態にて先端箇所３５の突部３７の斜面３９が延在する方向（上下方向から見て、前後方向Ｌ１から角度θ１だけ時計回りに回転した方向）からみたときの先端箇所３５の幅寸法ｂ（外側面３６の後端部４３と斜面３９との間隔）は、係止孔１５の開口幅寸法ｃより小さい（ｂ＜ｃ）（即ち、ｂ＜ｃ＜ａ）。なお、幅寸法ｂは、柱状箇所３４が湾曲して先端箇所３５が上下方向から見て角度θ１だけ反時計回りに傾いた状態にて、前後方向（柱軸方向）Ｌ１から見たときの先端箇所３５の幅寸法、と同義であり、そのように定義することもできる。 When viewed from the direction in which the slope 39 of the protrusion 37 of the tip portion 35 extends in the state where the columnar portion 34 is not curved (the direction that is rotated clockwise from the front-rear direction L1 by the angle θ1 when viewed from the up-down direction). The width dimension b of the front end portion 35 (the distance between the rear end portion 43 of the outer side surface 36 and the inclined surface 39) is smaller than the opening width dimension c of the locking hole 15 (b<c) (that is, b<c<a ). The width dimension b is the tip when viewed from the front-rear direction (column axis direction) L1 in a state where the columnar portion 34 is curved and the tip portion 35 is tilted counterclockwise by an angle θ1 when viewed from the up-down direction. It is synonymous with the width dimension of the point 35, and can be defined as such.

係止孔１５の外側斜面１７が延在する傾斜軸方向Ｌ２から見たときの係止孔１５の開口幅寸法ｄ（頂面２１の前端部２４と外側斜面１７との間隔）は、係止孔１５の開口幅寸法ｃより大きい（ｃ＜ｄ）。 The opening width dimension d of the locking hole 15 (the distance between the front end portion 24 of the top surface 21 and the outer slope 17) when viewed from the inclined axis direction L2 in which the outer inclined surface 17 of the locking hole 15 extends is It is larger than the opening width dimension c of the hole 15 (c<d).

次いで、図５を参照しながら、パッキン３のハウジング２への組み付けの際における、パッキン３の係止部３２の弾性変形の態様の推移について説明する。パッキン３の係止部３２のハウジング２の係止孔１５への挿入が進行すると、まず、図５（ａ）に示すように、係止部３２の先端箇所３５における突部３７（より正確には斜面３９）が係止孔１５の突部１９（より正確には内側斜面２３）に当接する。 Next, with reference to FIG. 5, the transition of the elastic deformation mode of the locking portion 32 of the packing 3 when the packing 3 is assembled to the housing 2 will be described. As the insertion of the locking portion 32 of the packing 3 into the locking hole 15 of the housing 2 progresses, first, as shown in FIG. 5A, the protrusion 37 (more accurately, at the tip end portion 35 of the locking portion 32). The slope 39) abuts the projection 19 of the locking hole 15 (more accurately, the inner slope 23).

この状態から挿入が更に進行すると、突部３７が突部１９から幅方向外側（図５（ａ）において右側）に押圧されることで、柱状箇所３４が幅方向外側に弾性変形して突部３７が突部１９の頂面２１に乗り上げられる。これにより、先端箇所３５が幅方向外側にオフセットされる（図５（ａ）中の白矢印を参照）。 When the insertion further proceeds from this state, the protrusion 37 is pressed outward in the width direction (right side in FIG. 5A) from the protrusion 19, and the columnar portion 34 is elastically deformed outward in the width direction and the protrusion is formed. 37 rides on the top surface 21 of the protrusion 19. As a result, the tip portion 35 is offset outward in the width direction (see the white arrow in FIG. 5A).

挿入が更に進行すると、図５（ｂ）に示すように、幅方向外側にオフセットされた状態にある先端箇所３５が、係止孔１５の外側斜面１７に当接する。この状態から挿入が更に進行すると、先端箇所３５が外側斜面１７から幅方向内側（図５（ｂ）において左側）に押圧されることで、柱状箇所３４が窪み４２を起点として湾曲して、先端箇所３５が上下方向から見て反時計回り（即ち「所定の向き」）に傾く（図５（ｂ）中の白矢印を参照）。 When the insertion further proceeds, as shown in FIG. 5B, the tip end portion 35, which is offset outward in the width direction, comes into contact with the outer inclined surface 17 of the locking hole 15. When the insertion further proceeds from this state, the tip end portion 35 is pressed from the outer inclined surface 17 to the inner side in the width direction (left side in FIG. 5B), so that the columnar portion 34 is curved starting from the recess 42, and the tip end portion 35 is bent. The point 35 inclines counterclockwise (that is, "predetermined direction") when viewed from above and below (see the white arrow in FIG. 5B).

このとき、先端箇所３５は、およそ角度θ１（図６（ｂ）参照）だけ反時計回りに傾く。この結果、先端箇所３５の斜面３９が、頂面２１に対して略平行に対向する状態となる。即ち、先端箇所３５が傾かない場合と比べて、上述した「ｂ＜ｃ及びｃ＜ｄ」の関係に起因して、先端箇所３５が係止孔１５を通過し易くなる。 At this time, the tip end portion 35 is inclined counterclockwise by an angle θ1 (see FIG. 6B). As a result, the inclined surface 39 of the tip end portion 35 is in a state of facing the top surface 21 substantially in parallel. That is, as compared with the case where the tip portion 35 is not inclined, the tip portion 35 is more likely to pass through the locking hole 15 due to the relationship of “b<c and c<d” described above.

この状態から挿入が更に進行すると、図５（ｃ）に示すように、先端箇所３５の突部３７が係止孔の突部１９を乗り越える。この結果、上述した先端箇所３５のオフセットが解除され、且つ、柱状箇所３４の湾曲の解除により先端箇所３５の傾きが解除される（図５（ｃ）の白矢印を参照）。そして、先端箇所３５の突部３７の後端面４１が係止孔１５の突部１９の前端面２２に係止されて、パッキン３のハウジング２への組み付けが完了する。以上、パッキン３のハウジング２への組み付けの際における、パッキン３の係止部３２の弾性変形の態様の推移について説明した。 When the insertion further proceeds from this state, as shown in FIG. 5C, the protrusion 37 of the tip end portion 35 gets over the protrusion 19 of the locking hole. As a result, the offset of the tip portion 35 described above is released, and the inclination of the tip portion 35 is released by releasing the bending of the columnar portion 34 (see the white arrow in FIG. 5C). Then, the rear end surface 41 of the projection 37 of the tip end portion 35 is locked to the front end surface 22 of the projection 19 of the locking hole 15, and the assembly of the packing 3 to the housing 2 is completed. The transition of the elastic deformation of the locking portion 32 of the packing 3 when the packing 3 is assembled to the housing 2 has been described above.

＜作用・効果＞
以上、本発明の実施形態に係るコネクタ１によれば、ハウジング２とパッキン３との組み付けの際、パッキン３の本体部３１から延びる柱状の係止部３２の先端箇所３５があらかじめ設計された「所定の向き」に傾くように、係止部３２の柱状箇所３４が湾曲する。係止部３２の先端箇所３５は、柱状箇所３４が湾曲していない状態にて前後方向から見たときの先端箇所３５の大きさ（図６（ｂ）に示す幅寸法ａ）よりも、柱状箇所３４が湾曲して先端箇所３５が前後方向に対して「所定の向き」に傾いた状態にて前後方向から見たときの先端箇所３５の大きさ（幅寸法ｂ）の方が小さい（ｂ＜ａ、図６（ｂ）参照）。そのため、係止部３２の先端箇所３５が「所定の向き」に傾くことで、先端箇所３５がハウジング２の係止孔１５を通り易くなる。 <Action/effect>
As described above, according to the connector 1 of the embodiment of the present invention, when the housing 2 and the packing 3 are assembled, the tip end portion 35 of the columnar locking portion 32 extending from the main body 31 of the packing 3 is designed in advance. The columnar portion 34 of the locking portion 32 is curved so as to tilt in the “predetermined direction”. The tip portion 35 of the locking portion 32 has a columnar shape rather than the size (width dimension a shown in FIG. 6B) of the tip portion 35 when viewed from the front-rear direction in a state where the columnar portion 34 is not curved. The size (width dimension b) of the tip end portion 35 when viewed from the front-rear direction in a state where the point 34 is curved and the tip end portion 35 is inclined in the “predetermined direction” with respect to the front-rear direction is smaller (b <a, see FIG. 6B). Therefore, the tip portion 35 of the locking portion 32 is inclined in the “predetermined direction”, so that the tip portion 35 can easily pass through the locking hole 15 of the housing 2.

よって、パッキン３をゴムなどの柔軟な材料で構成した場合であっても、従来のコネクタのように係止部３２がランダムな方向に曲がるのではなく、先端箇所３５が係止孔１５を通り易くなる「所定の向き」に係止部３２が湾曲するため、両者の組み付けを適正に行い得る。また、パッキン３をある程度硬質な材料で構成しても、上述したように先端箇所３５が係止孔１５を通り易いため、両者の組み付けを適正に行い得る。 Therefore, even when the packing 3 is made of a flexible material such as rubber, the locking portion 32 does not bend in a random direction unlike the conventional connector, but the tip portion 35 passes through the locking hole 15. Since the locking portion 32 is curved in the “predetermined direction” that facilitates the assembly, both can be properly assembled. Even if the packing 3 is made of a material that is hard to some extent, since the tip portion 35 easily passes through the locking hole 15 as described above, the both can be properly assembled.

このように、本発明の実施形態に係るコネクタ１によれば、係止部３２が湾曲する向きを意図的に制御することで、ハウジング２とパッキン３との組み付けの容易さと、パッキン３による止水性の向上と、を両立可能となっている。 As described above, according to the connector 1 of the embodiment of the present invention, by intentionally controlling the bending direction of the locking portion 32, the assembly of the housing 2 and the packing 3 is facilitated, and the locking by the packing 3 is performed. It is possible to achieve both improvement of water quality.

更に、本発明の実施形態に係るコネクタ１によれば、係止部３２の柱状箇所３４に窪み４２が設けられ、この窪み４２を起点として先端箇所３５が「所定の向き」に傾く。よって、窪み４２の位置や大きさ等を調整することで、先端箇所３５の傾きを任意に制御できることになる。 Furthermore, according to the connector 1 of the embodiment of the present invention, the columnar portion 34 of the locking portion 32 is provided with the depression 42, and the tip portion 35 inclines in the “predetermined direction” with the depression 42 as the starting point. Therefore, by adjusting the position, size, etc. of the depression 42, the inclination of the tip end portion 35 can be arbitrarily controlled.

更に、本発明の実施形態に係るコネクタ１によれば、係止孔１５の孔内面のうちの係止部３２の柱状箇所３４の窪み４２に向かい合う部分（即ち、外側斜面１７）が、前後方向に対して「所定の向き」に傾いた傾斜軸方向Ｌ２（図６（ｂ）参照）に沿うように傾いている。よって、窪み４２を起点に係止部３２の柱状箇所３４が湾曲し、湾曲した柱状箇所３４が係止孔１５の孔内面に向けて突出しても、柱状箇所３４が孔内面に突き当たり難い。よって、係止部３２の先端箇所３５が「所定の向き」に傾くように、柱状箇所３４を適正に湾曲させることができる。 Furthermore, according to the connector 1 according to the embodiment of the present invention, a portion of the inner surface of the locking hole 15 that faces the recess 42 of the columnar portion 34 of the locking portion 32 (that is, the outer slope 17) is a front-back direction. With respect to the tilt axis direction L2 (see FIG. 6B) that is tilted in the “predetermined direction”. Therefore, even if the columnar portion 34 of the locking portion 32 is curved starting from the recess 42 and the curved columnar portion 34 projects toward the inner surface of the hole of the locking hole 15, the columnar portion 34 is unlikely to hit the inner surface of the hole. Therefore, the columnar portion 34 can be appropriately curved so that the tip portion 35 of the locking portion 32 is inclined in the “predetermined direction”.

更に、本発明の実施形態に係るコネクタ１によれば、係止部３２の先端箇所３５と窪み４２とが連続するように、窪み４２が設けられている。ここで、係止部３２の先端箇所３５と窪み４２とが離れていると、係止部３２が湾曲した際、先端箇所３５と窪み４２との間にある部分が係止孔１５の孔内面に向けて突出し、この部分と孔内面との接触に起因し、先端箇所３５が係止孔１５を通過し難くなる懸念がある。しかし、係止部３２の先端箇所３５と窪み４２とが連続する場合、このような懸念がない。よって、ハウジング２とパッキン３との組み付けを更に適正に行い得る。 Further, according to the connector 1 according to the embodiment of the present invention, the recess 42 is provided so that the tip portion 35 of the locking portion 32 and the recess 42 are continuous. Here, when the tip portion 35 of the locking portion 32 and the recess 42 are separated from each other, the portion between the tip portion 35 and the recess 42 is the inner surface of the locking hole 15 when the locking portion 32 is curved. There is a concern that the tip end portion 35 may be difficult to pass through the locking hole 15 due to the contact between this portion and the inner surface of the hole. However, when the tip end portion 35 of the locking portion 32 and the recess 42 are continuous, there is no such concern. Therefore, the housing 2 and the packing 3 can be assembled more properly.

更に、本発明の実施形態に係るコネクタ１によれば、係止孔１５を前後方向から見たときの係止孔１５の開口の大きさ（図６（ｂ）における開口幅寸法ｃ）よりも、係止孔１５を傾斜軸方向Ｌ２から見たときの係止孔１５の開口の大きさ（開口幅寸法ｄ）が大きい（ｃ＜ｄ、図６（ｂ）参照）。よって、係止部３２の先端箇所３５が傾斜軸方向Ｌ２に沿った「所定の向き」に傾くことによる組み付け性の向上に加え、係止孔１５の見かけ上の開口が増大することにより、更にハウジング２とパッキン３との組み付けを適正に行い得る。 Furthermore, according to the connector 1 of the embodiment of the present invention, the size of the opening of the locking hole 15 when the locking hole 15 is viewed from the front-rear direction (opening width dimension c in FIG. 6B) is smaller than the size of the opening. The size of the opening of the locking hole 15 (opening width dimension d) when the locking hole 15 is viewed from the tilt axis direction L2 is large (c<d, see FIG. 6B). Therefore, in addition to the improvement in the assemblability by tilting the tip end portion 35 of the locking portion 32 in the “predetermined direction” along the tilt axis direction L2, the apparent opening of the locking hole 15 is further increased, The housing 2 and the packing 3 can be properly assembled.

更に、本発明の実施形態に係るコネクタ１によれば、係止部３２の先端箇所３５が係止孔１５に挿通される際、まず、先端箇所３５を突部１９に接触させることによって先端箇所３５を前後方向に対してオフセットさせて外側斜面１７に近付けるように変位させた後、先端箇所３５を外側斜面１７に接触させることによって先端箇所３５を「所定の向き」に傾けることができる。発明者による検討によれば、このように係止部３２の先端箇所３５を一旦オフセットさせた後に係止部３２の柱状箇所３４を湾曲させることで、係止部３２が湾曲する向きをより確実に制御できることが明らかになっている。よって、本発明の実施形態に係るコネクタ１の製造方法により、更にハウジング２とパッキン３との組み付けを適正に行い得る。 Furthermore, according to the connector 1 according to the embodiment of the present invention, when the tip end portion 35 of the locking portion 32 is inserted into the locking hole 15, first, the tip end portion 35 is brought into contact with the protrusion 19 so that the tip end portion 35 is contacted. After offsetting 35 with respect to the front-rear direction and displacing it so as to approach the outer slope 17, the tip 35 can be tilted in a “predetermined direction” by bringing the tip 35 into contact with the outer slope 17. According to the study by the inventor, by thus offsetting the tip end portion 35 of the locking portion 32 and then bending the columnar portion 34 of the locking portion 32, the direction in which the locking portion 32 bends is more reliable. It has become clear that it can be controlled. Therefore, the method of manufacturing the connector 1 according to the embodiment of the present invention can further properly assemble the housing 2 and the packing 3.
